Recollection versus Imagination: Exploring Human Memory and Cognition via Neural Language Models (2020.acl-main)
Copied to clipboard
| Challenge: | a dataset of imagined and recalled stories is used to study the cognitive processes involved in storytelling, contrasting imagination and recollection of events. |
| Approach: | They use a dataset of 7,000 stories to study the cognitive processes involved in storytelling, contrasting imagination and recollection of events. |
| Outcome: | The proposed measures show that imagined stories have a substantially more linear narrative flow compared to recalled stories in which adjacent sentences are more disconnected. |
Eeyore: Realistic Depression Simulation via Expert-in-the-Loop Supervised and Preference Optimization (2025.findings-acl)
Copied to clipboard
| Challenge: | Large Language Models (LLMs) have been explored for mental healthcare training and therapy client simulation, but they fail to authentically capture diverse client traits and psychological conditions. |
| Approach: | They propose an 8B model optimized for realistic depression simulation with expert input at every stage. |
| Outcome: | The model outperforms GPT-4o in linguistic authenticity and profile adherence. |
